IC revision1.0

Description

This evaluation board introduces a complete Infineon’s system solution for a 3 kW power supply unit (PSU) targeting the newly released OCP V3 rectifier specifications for servers and data centers.The PSU comprises a front-end AC-DC bridgeless totem pole converter followed by a back-end DC-DC isolated half-bridge LLC converter. The front-end totem pole converter provides power factor correction (PFC) and total harmonic distortion (THD). The LLC converter provides safety isolation and a tightly regulated output voltage.The measured peak efficiency of the complete PSU at 230 VAC is 97.5%, not including the internal fan, and 97.4%, including the internal fan. The overall outer dimensions of the PSU are 73.5 mm x 520 mm x 40 mm, which yields a power density in the range of 32 W/inch³ (1.95 W/cm³).

Features

  • Low capacitances
  • Optimized switching behavior at higher currents
  • Commutation robust fast body diode with low reverse recovery charge (Qrr)
  • Superior gate oxide reliability
  • Excellent thermal behavior
  • Increased avalanche capability
  • Works with standard drivers
  • 4-pin package

Typical applications

  • SMPS, UPS, Motor drives
  • Server, Telecom
  • Solar energy systems, Energy storage and battery formation,EV charging
